Matt stone and the “overdeification” of vitamin A.

Next question, Victoria Dale Harris says,
I just saw an email from Matt Stone referring the overly deified…. Oh someone had to bring this up! Okay! I just saw an email from Matt Stone referring
to the overly deified nutrient vitamin A. He’s referring it’s probably in asthma, but
right I believe the etiology of the condition could be nearly identical in inflammatory
conditions. Also a few bloggers are starting to spread
the word specifically Weston A. Price Foundation bloggers who are sick of really shitty results
on…. now have to mark this explicit in iTunes… really shitty results on a high-A diet. Any thoughts about this and comments about
Vitamin A toxic levels? Pamela Schoenfeld responds, for what it’s
worth, as a practicing dietitian I see a high percentage of individuals with signs of Vitamin
A deficiency. At least 25%. They see good outcomes with daily supplementation
between 3,000 to 10,000 IU. That comment did not go where I thought it
was going to go, which is to the guy that Matt Stone is being influenced by right now
about the Vitamin A toxicity so I’ll save that for another time when someone brings
that guy up. Okay so look I think that, yeah, you shouldn’t
deify any nutrient, right? Any point of view that breaks the world down
into good and bad molecules is a doomed-to-failure point of view because molecules don’t have
virtues, okay? Like, everything is about context, and too
much vitamin A, which cannot be defined outside
of context, not just what your needs are, not just what are your genetics, not just
what is your turnover rate, not just what is your eye color, not just are you getting
pregnant, but also the presence of other things in the diet. For example, vitamin D. For example, even vitamins E and K will affect
the vitamin A requirement because they all regulate each other’s breakdown. So look, some people have too much Vitamin
A. Some people take more vitamin A than they should. There’s dozens of case reports of vitamin
A toxicity, but there’s no evidence that people at normal intakes who are not supplementing
are getting inflammation from consuming dietary levels of vitamin A. And look at what what Pam said: “I see 25%
of people…” Who she sees, and every practitioner, does
not see a random sample of population, so like me, her, Chris Kresser, like anyone,
pick them, their sample is highly biased by the people who choose to come to them, but
25% she sees signs of vitamin A deficiency that respond to vitamin A supplementation. That’s a fairly large proportion, but look
at the amounts she’s using, 3,000 -10,000 IU is not a lot, the RDA’s 3,000, if you’re
correcting deficiency 10,000 is highly reasonable over a short period of time. And you know, but look if you have someone
who has a very long history of taking vitamin A
supplements at 30,000, 40,000, 50,000 IU over 3 years, then, yeah, they might have all kinds
of problems from that because they’re taking too much. And that’s way more likely when they’re not
taking vitamin D, when they’re not taking vitamin E, when they’re not taking vitamin
K, you’re taking this one vitamin at a very high dose, yes it will cause toxicity. There’s nothing remotely controversial about
that, no reason to question it. And there are probably a lot of people in
Weston A. Price who think that more of a good thing is better and who are taking, I know
for a fact that many people were taking two or three tablespoons of high vitamin cod liver
oil for many years and that was nuts, and it’s nuts now, and
they’re getting too many fat-soluble vitamins and too many polyunsaturated fatty acids from
high levels of cod liver oil like that. But 3 to 10,000 IU, even long-term there’s
no evidence that that causes toxicity, but some people are going to be intolerant. I know anecdotes, I know stories of people
who for some reason they take vitamin A at very low doses and it causes some hypersensitivity
reaction, I don’t know what causes it. So there will be stories of people who improve
when they take the vitamin A out of their diets. It will happen, it makes sense. And on top of that there are epidemic proportions
of people with fatty liver. What happens when fatty liver gets bad? The cells that store vitamin A in the liver
dump their vitamin A into the bloodstream so they can transform into cells that lay
scar tissue down in the liver. So people with fatty liver, which is about
three-quarters of people who are obese, right, so about 70 million Americans, maybe more
now, have fatty liver disease. Some proportion of them are laying down scar
tissue in their livers and they are losing the ability to properly store and metabolize
vitamin A. Could taking vitamin A out of the diet for
them help? Probably, but it’s a very, it’s a very, it’s
a, it’s a tough place to be in because in those cases those people are going to have
cellular vitamin A deficiency. So it’s like, do you save the liver or do
you save everything else? Well you might want to withdraw vitamin A
in those cases, and you might want to fix the obesity and the fatty liver disease, and
then restore the vitamin A that might be needed. But I have no problem saying
that some people get too much vitamin A, vitamin A can be toxic, but vitamin A, there are some
people going around right now that are saying that vitamin A is a toxin and it’s intrinsically
toxic and those people are truly absolutely nuts. I’m not saying that’s Matt Stone, I don’t
know if he’s saying that, but there are people, it’s becoming very popular to say that. That’s flat-earth level thinking that it’s
just intrinsically toxic and not a vitamin.

  1. Would vitamin K2 be taking in to high amount? I eat eats and other fold with K2. I did start taking K2 in 100 or 200 mcg six month ago. Is there normally to high amounts of vitamin K2 since it is fat soluble.

  3. I think that ironically vitamin A in higher doses can eat only healthy people with good metabolism, good thyroid and liver function. With good vitamin D level etc.. Because otherwise vitamin A looks like very good anti thyroid substance.. I have vitamin A in same category as PUFA fats and iron. We don't need a lot those things and for sure not from any supplements.. Vitamin A in creams, acne medications(NOBODY should take accutane EVER!!!) and retinol supplements and eating a lot of liver are very bad idea for 99% of people… I mean it is almost impossible to eat diet low in vitamin A (plant or animal sources..) and you will get RDA just from regular healthy diet with some eggs and vegetables, fruits… I know this very well since I am on low vit A diet for maybe 8 months and it is not fun(but worth it) to eat only grains and lean meat basically lol..
